Duffus loved potato chips almost as much as he loved his tea. The problem was when he had large family gatherings, all the kids would devour his snacks before he could. His marble game worked for a while, but his trick was soon found out. So, Duffus came up with another way to keep the snacks for himself and yet make it seem as though he wasn't the greedy snack hog he was. Duffus took two large bowls, one wood and one plastic, and placed them up high so that the kids couldn't see the contents.

He then said, "One is full and the other is empty. You get whatever is in the bowl you pick. You can pick only once, but you must decipher my clues and explain to me which bowl you think has the chips and why. And no random guessing allowed."

Hint

Answer

All the kids were stumped except one young girl who gave the correct answer.
The items made from synthetic materials (polyester, plastic, acrylic) all have something in them. The items made from natural materials (cotton, cardboard, paper) are all empty. Therefore the plastic bowl (being synthetic) has the chips and the wood bowl (being natural) is empty. Duffus had to hand over the chips and again was left plotting another snack game. But that's another teaser.Hide

i got that the clues were natural things/artificial things, and matched the bowls, but i couldn't work out which had the chips and which didn't (at least until i read the hint) - i kept trying to find a pattern.
good work
